FIG. 4 shows a block diagram of an implementation environment related to a method provided by an exemplary embodiment of the present disclosure. As shown in FIG. 4, the implementation environment includes a first terminal 401, a second terminal 402, a third terminal 403, and a server 404. The first terminal 401, the second terminal 402 and the third terminal 403 may be devices such as a smartphone. A terminal corresponding to a first telephone number is the first terminal 401, a terminal corresponding to a second telephone number is the second terminal 402, and a terminal corresponding to a telephone number of a recommender is the third terminal 403, and the present embodiment does not impose specific limitations on this. A user using the third terminal 403 may recommend the telephone number of a user using the second terminal 402 to a user using the first terminal 401. Through the implementation environment as shown in FIG. 4, the first terminal 401, the second terminal 402, the third terminal 403, and the server 404 may communicate with each other through networks.

For purposes of convenience in description, FIG. 4 only shows the first terminal 401, the second terminal 402, the third terminal 403, and the server 404. The first terminal 401, the second terminal 402, and the third terminal 403 represent one terminal among a plurality of terminals, respectively. The embodiments of the present disclosure will be illustrated hereinafter by realizing prompting as to an incoming call through the information interaction among the first terminal 401, the second terminal 402, the third terminal 403, and the server 404.

With reference to the above embodiment and the implementation environment as shown in FIG. 4, FIG. 5 shows a flow chart of a method for acquiring recommending information according to an exemplary embodiment. As shown in FIG. 5, the method for acquiring recommending information is applied in a terminal, and the method includes the following steps.

In step 501, a server receives a request for recommending information, and generates recommending information according to the request for recommending information. The recommending information is configured to indicate that a recommender recommends a second telephone number to a terminal affiliated with a first telephone number.

Before the server receives the request for recommending information, a recommender may recommend a second telephone number to a user corresponding to a first telephone number. For example, the recommender is a user B, the user corresponding to the first telephone number is a user A, and the user corresponding to the second telephone number is a user C, and then the user B may recommend the telephone number of the user C to the user A.

The manners for the recommender recommending the second telephone number to the user corresponding to the first telephone number will not be specifically defined in the embodiment, and the manners include but not limited to: recommending the second telephone number to the user corresponding to the first telephone number through an application message, wherein the application message includes the second telephone number. Or, a short message including the second telephone number may also be sent to the user corresponding to the first telephone number, thus recommending the second telephone number to the user corresponding to the first telephone number.

Accordingly, the first terminal corresponding to the first telephone number may receive the second telephone number sent by the recommender. The manners for the first terminal corresponding to the first telephone number receiving the second telephone number sent by the recommender will not be specifically defined in the embodiment, and the manners include but not limited to: when receiving a short message sent by the recommender, performing telephone number identification on the short message; and when obtaining a telephone number via the identification, taking the telephone number extracted and identified from the short message as the second telephone number; or, when receiving an application message, performing telephone number identification on the application message; and when obtaining a telephone number via the identification, taking the telephone number extracted and identified from the application message as the second telephone number.

It should be noted that the first terminal may acquire a telephone number from which the short message is sent, when the short message sent by the recommender is received, and the present embodiment does not impose specific limitations on this. Or, when receiving the application message sent by the recommender, the first terminal may acquire a telephone number bound to a user account from which the application message is sent, and take the acquired telephone number as the telephone number of the recommender, and the present embodiment does not impose specific limitations on this. When the recommender sends the application message to the first terminal, the recommender sends the application message to the first terminal through an application account number; therefore, the first terminal cannot directly acquire the telephone number of the recommender. Thus, the first terminal may send a request for acquiring telephone number to the server, and the server, after receiving the request for acquiring telephone number, returns the telephone number to the first terminal, so that the first terminal takes the received telephone number as the telephone number of the recommender.

Moreover, after the recommender recommends the second telephone number to the user corresponding to the first telephone number, the recommender may also send a message to the user corresponding to the second telephone number, so as to prompt the user corresponding to the second telephone number that the telephone number of the user corresponding to the second telephone number has already been recommended to the user corresponding to the first telephone number, and the present embodiment does not impose specific limitations on this. For instance, the recommender is the user B, the user corresponding to the first telephone number is the user A, and the user corresponding to the second telephone number is the user C. The user B, after recommending the telephone number of the user C to the user A, may send the following message to the user C: “I have already recommended your telephone number to the user A”, so that the user C, after receiving the message sent by the user B, can confirm that the telephone number of himself/herself has already been known by the user A.

The manners for the server receiving the request for recommending information will not be specifically defined in the embodiment, and the manners include but not limited to: receiving the request for recommending information sent by a first terminal corresponding to the first telephone number; or, receiving the request for recommending information sent by a third terminal corresponding to the telephone number of the recommender.

For instance, the recommender is the user B, the user corresponding to the first telephone number is the user A, and the user corresponding to the second telephone number is the user C. After the user B recommends the telephone number of the user C to the user A, for example, after the user B sends a short message including the telephone number of the user C to the user A, the third terminal corresponding to the user B may send a request for recommending information to the server, so that the server may receive the request for recommending information sent by the third terminal corresponding to the telephone number of the recommender. Or, after the user A receives the telephone number of the user C recommended by the user B, for example, after the user A receives the short message including the telephone number of the user C sent by the user B, the first terminal corresponding to the user A may send a request for recommending information to the server, so that the server may receive the request for recommending information sent by the first terminal corresponding to the first telephone number.

The request for recommending information may include the telephone number of the recommender, the first telephone number and the second telephone number. For instance, the recommender is the user B, the user corresponding to the first telephone number is the user A, and the user corresponding to the second telephone number is the user C. The request for recommending information may include the telephone number of the user B, the telephone number of the user A and the telephone number of the user C, and the format of the request for recommending information may be {B, {A}, C}, and the formats of the request for recommending information will not be specifically defined in the embodiment.

It should be noted that the request for recommending information received by the server may either be sent by the first terminal corresponding to the first telephone number, or sent by the third terminal corresponding to the telephone number of the recommender. When the request for recommending information is sent by the third terminal corresponding to the telephone number of the recommender, since the recommender may possibly recommend the second telephone number to multiple users, the telephone numbers of multiple users receiving the recommended telephone number may possibly be included in the request for recommending information sent by the third terminal corresponding to the telephone number of the recommender, and the present embodiment does not impose specific limitations on this. For instance, after the user B recommends the telephone number of the user C to the user A, a user D and a user E, the third terminal corresponding to the user B may send a request for recommending information in a format of {B, {A, D, E}, C} to the server.

The first terminal may send the request for recommending information to the server according to the first telephone number of the first terminal, the telephone number of the recommender and the second telephone number, and the manners for the first terminal sending the request for recommending information to the server will not be specifically defined in the embodiment. The first terminal may send the request for recommending information to the server when detecting a dialing request to the second telephone number in a current display page, and the timing for the first terminal sending the request for recommending information to the server will not be specifically defined in the embodiment.

The third terminal may send the request for recommending information to the server according to the telephone number of the recommender, the first telephone number and the second telephone number, and the manners for the third terminal sending the request for recommending information to the server will not be specifically defined in the embodiment.

Moreover, when the user corresponding to the second telephone number is an online user, the server can send the recommending information to the second terminal corresponding to the second telephone number subsequently. Therefore, before the server receives the request for recommending information sent by the first terminal corresponding to the first telephone number, the first terminal may send a query request to the server. The server may receive the query request sent by the first terminal corresponding to the first telephone number, and determine whether the user corresponding to the second telephone number is an online user according to the second telephone number in the query request, and thus return a query result to the first terminal, and the present embodiment does not impose specific limitations on this. The query request includes at least the second telephone number, and the contents of the query request will not be specifically defined in the embodiment.

After receiving the query result returned by the server, if the query result is that the user corresponding to the second telephone number is an online user, the first terminal performs the step of sending the recommending information to the server. The server may determine a user account associated with the second telephone number, and determine whether the user is an online user according to the login conditions of the user account. For example, the server may determine whether the user account associated with the second telephone number is logged in currently or has been logged in within recent one month, and the like. If the user account is logged in currently or has been logged in within recent one month, then the user is determined as an online user.

Or, before the server receives the request for recommending information sent by the third terminal corresponding to the telephone number of the recommender, the server may receive a query request sent by the third terminal corresponding to the telephone number of the recommender. The query request includes at least the second telephone number. The server may determine whether the user corresponding to the second telephone number is an online user according to the second telephone number in the query request, and return a query result to the third terminal. After receiving the query result returned by the server, if the user corresponding to the second telephone number is an online user, the third terminal may perform the step of returning the request for recommending information to the server.

It should be noted that the first terminal may also send expiry time corresponding to the request for recommending information to the server, and the present embodiment does not impose specific limitations on this. After receiving the expiry time sent by the first terminal, the server may determine whether corresponding request for recommending information is expired according to the expiry time. When the request for recommending information is expired, the request for recommending information is removed. Since the expired request for recommending information can be removed according to the expiry time, over occupation of the storage space of the server due to storage of too many requests of recommending information can be avoided, and thereby the storage space of the server is saved.

The manners for the server generating the recommending information according to the request for recommending information will not be specifically defined in the embodiment, and the manners include but not limited to: determining the first telephone number, the telephone number of the recommender and the second telephone number according to the request for recommending information; and generating the recommending information according to the first telephone number, the telephone number of the recommender and the second telephone number. For example, the telephone number of the recommender is B, the first telephone number is A, and the second telephone number is C. Corresponding recommending information generated by the server may be {B, {A}, C}.

In step 502, the server sends the recommending information to the second terminal corresponding to the second telephone number according to the second telephone number in the recommending information.

The manners for the server sending the recommending information to the second terminal corresponding to the second telephone number according to the second telephone number in the recommending information will not be specifically defined in the embodiment, the manners include but not limited to: sending the recommending information to the second terminal corresponding to the second telephone number through a network in a form of data packet. The data packet includes the recommending information.

In step 503, the second terminal receives the recommending information sent by the server, searches whether the telephone number of the recommender in the recommending information is stored in a local contact list. If the telephone number of the recommender in the recommending information is stored in the local contact list, then step 504 is performed. If the telephone number of the recommender in the recommending information is not stored in the local contact list, then the flowchart is ended.

Since subsequent steps cannot be performed unless the recommender is a contact of the user corresponding to the second terminal, the second terminal, after receiving the recommending information sent by the server, needs to search whether the telephone number of the recommender in the recommending information is stored in the local contact list, and thereby determines whether the recommender is a contact of the user corresponding to the second terminal. When the second terminal searches whether the telephone number of the recommender in the recommending information is stored in the local contact list, if the telephone number of the recommender in the recommending information is not stored in the local contact list, it indicates that the recommender is not a contact of the user corresponding to the second telephone number. Therefore, the recommending information can be deemed invalid information and then removed, and meanwhile the flowchart is ended, and the present embodiment does not impose specific limitations on this.

In step 504, if the telephone number of the recommender in the recommending information is stored in the local contact list, the second terminal stores the recommending information in a local information database.

In order to save local storage resources, expiry time corresponding to the recommending information can be acquired when the second terminal stores the recommending information to the local information database. Accordingly, when storing the recommending information to the local information database, the recommending information and the expiry time corresponding to the recommending information may be stored in the local information database, and the present embodiment does not impose specific limitations on this. Based on the above contents, the second terminal may determine whether the recommending information is expired according to the expiry time corresponding to the recommending information. If the recommending information is expired, then the recommending information and the expiry time corresponding to the recommending information are removed from the local information database, and the present embodiment does not impose specific limitations on this. For example, the recommending information is {B, {A}, C}. Then, the expiry time corresponding to the recommending information may be stored in the following forms, such as {B, {A}, C, t}. After this piece of recommending information is stored, timing may be started from the storing moment. When the accumulated time period exceeds the expiry time t, for instance, the time period exceeds 10 days, then the recommending information is determined as expired, and the recommending information and the expiry time corresponding to the recommending information {B, {A}, C, t} are removed from the local information database.

It should be noted that the process in the above steps 501 to 504 is the process for the second terminal storing the information database including the recommending information locally. Through the locally stored information database, when the second terminal receives an incoming call, the second terminal may perform prompting as to an incoming call according to the information database. The specific process is as shown in the following steps.

In step 505, when the second terminal receives an unknown call, the second terminal determines whether the local information database includes designated recommending information corresponding to the unknown call. The information database is configured to store the recommending information sent by the server, and the designated recommending information is configured to indicate that the recommender recommends the second telephone number used by the current terminal to the first telephone number. If the second terminal determines that the local information database includes the designated recommending information corresponding to the unknown call, then step 506 is performed. If the second terminal determines that the local information database does not include the designated recommending information corresponding to the unknown call, then the flowchart is ended.

After receiving an incoming call, the second terminal may search whether the calling number is stored in the local contact list. When the calling number is in the local contact list, it indicates that a user corresponding to the calling number is a contact of the user using the second terminal. At this moment, prompting as the incoming call can be performed according to normal flows. When the calling number is not stored in the local contact list, it indicates that the user corresponding to the calling number is not a contact of the user using the second terminal. At this moment, the call received by the user using the second terminal is an unknown call. The method provided by the embodiment mainly explains the situation where the incoming call is an unknown call. In embodiments of the present disclosure, the telephone number corresponding to the unknown call is the first telephone number.

Based on the contents in the above step 501, the manners for the second terminal determine whether the local information database includes the designated recommending information corresponding to the unknown call will not be specifically defined in the embodiment, and the manners include but not limited to: determining whether the recommending information including the first telephone number is stored in the local information database.

For instance, three pieces of recommending information are stored in the local information database, and the user corresponding to the first telephone number is the user A. The three pieces of recommending information are {B, {A}, C}, {B, {D}, C} and {E, {F}, C}, respectively. Since the recommending information {B, {A}, C} in the local information database includes the telephone number of the user A, i.e., the recommending information includes the first telephone number, and thus the recommending information {B, {A}, C} may be determined as the designated recommending information, i.e., the local information database includes the designated recommending information. When the following two pieces of recommending information are stored in the local information database: {B, {D}, C} and {E, {F}, C}, for example, then it may be determined that the local information database does not include the designated recommending information according to the above determination process.

If the second terminal determines that the local information database includes the designated recommending information corresponding to the unknown call, then it indicates that the user corresponding to the unknown call acquires the second telephone number corresponding to the second terminal through the recommendation of a contact of the user corresponding to the second terminal. At this moment, step 506 may be continuously performed. If the second terminal determines that the local information database does not include the designated recommending information corresponding to the unknown call, then it indicates that the user corresponding to the unknown call is not recommended by a contact of the user corresponding to the second terminal. At this moment, the second terminal can perform prompting as to the unknown call using an ordinary manner, and meanwhile the flowchart is ended.

In step 506, when the information database includes the designated recommending information, the second terminal performs prompting as to the unknown call according to the designated recommending information.

The manners for performing prompting as to the unknown call according to the designated recommending information will not be specifically defined in the embodiment, the manners include but not limited to: determining whether the recommender in the designated recommending information is in a local contact list according to the telephone number of the recommender in the designated recommending information; and when the recommender in the designated recommending information is in the local contact list, performing prompting as to the unknown call according to the information of the recommender.

Since the designated recommending information includes the telephone number of the recommender and subsequent prompting as to an incoming call needs to be performed according to the information of the recommender in the local contact list, the second terminal needs to determine whether the recommender in the designated recommending information is in the local contact list. The manners for performing prompting as to the unknown call according to the information of the recommender will not be specifically defined in the embodiment, the manners include but not limited to: generating a corresponding prompting text according to the information of the recommender; and displaying the prompting text to perform prompting as to the current incoming call. Rather, prompting as to the current incoming call may be performed using such manners as voice prompting, picture prompting, and the like, and the present embodiment does not impose specific limitations on this.

For instance, the information of the recommender is the name of the recommender, and the name of the recommender is B. The following prompting text may be generated according to the information of the recommender: “Your number is recommended by B”, so that the prompting text may be displayed in a display screen of the second terminal when an unknown call is received. Specific display effects are shown in FIG. 6.

Moreover, the user corresponding to the first telephone number is not an unknown user any longer to the user of the second terminal when the first telephone number corresponding to the unknown call is stored in the local contact list of the second terminal. For example, the telephone number recommending information {B, {A}, C} is stored in the local information database, and when the user C receives a call from the user A, the user C may not know the user A since the telephone number of the user A is not stored in the local contact list; thus, the second terminal used by the user C will perform prompting as to the unknown call according to the foregoing process. When the telephone number of the user A is stored in the local contact list by the user C, then the user A is not an unknown user any longer to the user C.

Therefore, after performing of prompting as to the unknown call according to the designated recommending information, if it is that the first telephone number in the recommending information is stored in the local contact list, the recommending information is removed from the local contact list, the present embodiment does not impose specific limitations on this. For instance, in the foregoing examples, after the telephone number of the user A is stored in the local contact list, the second terminal may remove the telephone number recommending information {B, {A}, C} from the local information database.

It should be noted: it may be known from the foregoing step 502 that, since the telephone numbers of multiple users receiving the recommended telephone number may be stored in the recommending information, for example, {B, {A, D, E}, C}, the recommending information can be removed after it is detected that the telephone numbers of multiple users receiving the recommended telephone number in the recommending information are stored in the local contact list at the same time. For example, after it is detected that the telephone numbers of the user A, the user D and the user E are stored in the local contact list at the same time, the recommending information {B, {A, D, E}, C} may be removed from the local information database.

According to the method provided by embodiments of the present disclosure, when the second terminal receives an unknown call, whether the local information database includes the designated recommending information corresponding to the unknown call is determined, and when the information database includes the designated recommending information, prompting as to the unknown call is performed according to the designated recommending information. Since prompting as to a current incoming call may be performed according to the recommending information, a user can conveniently communicate with a user of the unknown call. Therefore, the prompting as to incoming call has better flexibility, and better effects are obtained
